**** dogfoot note ****

Rhino사의 nurbs 취급 라이브러리인 opennurbs 를 mingw로 컴파일 하기 위해서 약간의 수정이 필요한데..
https://www.rhino3d.com/kr/opennurbs/

본 소스는 현재 최신버전으로 아래에서 받았음.
https://github.com/mcneel/opennurbs/archive/refs/tags/v7.6.21127.19001.tar.gz

기본으로 opennurbs 는 윈도우즈상에서의 컴파일은 VC++ 7.0 & 9.0 Community 버전만 지원함.
난 MinGW 를 주로 쓰기 때문에 직접 opennurbs 코드를 수정해서 컴파일 및 테스트까지 성공한 diff 를 올려둠

opennurbs-7.6.21127.19001.diff.zip

그리고 컴파일을 위해서는 MinGW용 uuid가 필요함. (http://blog.tcltk.co.kr/?p=4434)

사용된 MinGW g++ 버전은 아래와 같음

[MIN@DESKTOP-RSH0QT3 build]$ g++ --version
g++.exe (Rev2, Built by MSYS2 project) 10.3.0
